针对卫星快速机动的需求,提出一种动量轮混合配置的策略,给出在系统故障重构且维持整星零动量情况下,混合轮系中各动量轮标称角动量的分配方法以及力矩分配矩阵的算法,使得重构后单轴能够输出最大力矩.计算结果表明新算法能有效降低小力矩动量轮饱和带来的不利影响,增强了系统的控制能力.
Aiming at the demand of satellite rapid maneuver, a hybrid strategy of momentum and momentum is proposed. The method of distributing the nominal angular momentum of each momentum wheel and the torque distribution in the case of reconfiguration of the system and maintaining zero-momentum of the whole satellite system are given. Matrix algorithm, the maximum torque can be output by the single shaft after reconstruction.The calculation results show that the new algorithm can effectively reduce the adverse effects caused by saturation of the small moment momentum wheel and enhance the control ability of the system.
